Transcatheter aortic valve implantation (TAVI) offers a less invasive treatment alternative to surgical aortic valve replacement for high-risk patients. Although the procedure can be performed at low risk, life-threatening complications may arise in single cases during or even months after the procedure. Here, the details are presented of two patients who underwent TAVI by a transfemoral approach with Medtronic CoreValve prostheses and suffered myocardial |
ischemia months later. The patients’ anatomy with small aortic root, narrow sinus of Valsalva and small distance between the annulus base and coronary arteries and/or the relative oversizing of the CoreValve prosthesis with a high positioning may have contributed to this late complication. Hence, caution is mandatory in this type of patient, with exact pre-procedural planning and close follow up required. The Journal of Heart Valve Disease 2013;22:762-766 |
